    Took for a data log session and went to use Dave W $OE etc... fixer spreadsheet and it did not work? I have used the 7747 side and it was wonderful... so I looked at BLM history tables in A219_0E_31_v250 and they were not correct to XDF fueling table and Dave's VE fixer spread sheet so I had to rebuild them.

    Took 2 data log rounds of about 15 minutes each to get VE perfect then did spark and found the stock knock sensor works nicely on the IH motor. Got spark dialed in and had to redo VE tables and she's now running like a charm.

    Here's the new $OE.adx with corrected BLM history tables.

    I posted some notes about the histogram here:

    The new.adx file is a good fix.

    I remember reading that now and could not understand why it was so complicated till I used it. I sent 93V8S10 a PM and he said the changes I made to BLM historyGram would be part of next build.

    It is strange how $OE uses the table RPM vs MAP you posted is exactly for spark, but in fuel, off idle and near idle it does not go all the way up in 5 kpa increments. It stops at 40 and goes up in 10 KPA increments. Less columns, that is why you showed to highlght them that way!

    Anyway just a small glitch in otherwise excellent ADX now that I have a vehicle to use it on a regular basis!

    And your VE fixer is sweet once again!

    Runs so sweet! Just turn the key! Only issue since start up has been a throttle kicker code 36? then we cleared it and ran fine, IAC was working fine and Code 36 came back and then code 35 IAC. So we changed out the IAC and driven back and forth to work and no more codes. So I guess the IAC was faulty?

    Still running without VSS but still 500% better than a carb and points, can't wait to get that in.

    Since you jeep guys were having knock sensor issues da-kid got a new knock sensor from work and we installed it with three wraps of teflon tape torqued to 14 lbs and never had a knock on stock BB timing. Once I started adding spark to catch up to what IH has from factory I could start to get some knock retard without hearing a thing! So I'd say it's working nicely in the IH motor. Motor was fresh just a 1000 or 2 miles ago so no old engine noises.

    Has an open element air filter as the chevy truck air filter we got with cold air intake and hot air tube hit the thermastat housing, so need to do something there.

    Going to add IAT when that's done. Going to add the oil temp sensor in oil drain plug next oil change. Going to add VSS. But overall went very well!

    I had the same thing on mine. I kept getting the throttle kicker code, and sometimes the IAC code with it. I knew it wasnt the IAC cause it was new. So I simply disabled the error code for the throttle kicker, and I have never had a IAC code pop up ever again.

    Hmmm? Well we just swapped out the IAC with another used one and no error code any more... which is strange because the IAC was part of the entire system I had running on bench without issue.

    Comparing bins it looks like throttle kicker is a manual trans thing and stall saver is an auto trans thing? Some are same, haven't figured it out totally yet...
